A. Too look at B. Looking at C. Looked at D. To be looked at
He came in, followed by a group of reporters.
having done结构:分词与句子主语是主谓关系,切发生在谓语动词之前。Having seen the film already, I declined his invitation to go to the cinema.
having been done结构:该结构表示完成被动,即分词与句子主语之间是动宾关系,且发生在谓语动词之前。如:Having been showed many times, he still didnt understand the operation of the machine.
to do 结构:这是不定式结构,在句中可以做目的状语,也可以做结果状语,但不定式动作总是发生在谓语动词之后。如:
_______ a teacher in a university, it is necessary to have at least a masters degree.
A. To become B. Become C. One becomes D. On becoming
表结果时一般为固定结构,如too to, enough to.,或是表示出乎意料的结果,常可加构成only to的结构。如:
I did what I could to comfort her only to make her cry even more. The next day, she woke to find herself in hospital.
being done结构:该结构表示被动与正在进行,一般置于句首,表示原因。如:Being chased by some spies, he hid himself in the grass.
做表语
测试中对表语的考查主要侧重在现在分词与过去分词的区别上,所以对于做表语的非谓语动词,主要看分词与句子主语之间的关系。做表语的分词一般只有doing和done两种形式。现在分词表示做表语的与主语是主谓关系;过去分词表示做表语的与主语之间是动宾关系。根据使用规律,如果主语是无生命名词,则表语分词为现在分词;如果主语是有生命名词,以过去分词居多,但也可以用现在分词,但意思不同。如:
